ME631 is a versatile three-phase power meter engineered for comprehensive energy monitoring and power quality analysis. It captures critical electrical parameters in real-time—including voltage, current, power types (active, reactive, apparent), power factor, and harmonic distortion—enabling precise system diagnostics.
Featuring an intuitive hierarchical menu system, users navigate dedicated sections for voltage, current, power, energy, and harmonic data via physical buttons. Its adaptable design supports diverse industrial setups through compatibility with external sensors like CTs or Rogowski coils and multiple wiring configurations.
Communication leverages RS-485 with MODBUS RTU protocol for remote monitoring, while programmable relay outputs enable alarms or control actions. Advanced functionalities include tariff-based energy management, sensor calibration tools, and optional data logging for long-term analysis.
Designed for reliability in demanding environments, the meter adheres to industrial standards for electrical safety and environmental resilience. Simplified installation via DIN-rail mounting and clear wiring guidelines makes it ideal for energy audits, load optimization, and power system diagnostics.
